1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

Background and Aims: Internet Gaming Disorder (IGD) is a psychological condition that impairs various aspects of life, with adolescents being particularly vulnerable due to developmental factors and heightened digital exposure. This study aims to explore the interplay between behavioral and neural bases of the development of IGD, offering insights for possible prevention strategies. Methods: A large sample of young adults (n = 1,205, age (SD) = 18.80 (1.26)) was assessed for impulsivity, sensation seeking, and IGD tendency. Two year later, impulsivity and IGD tendency were evaluated again, to expose possible long-term effects. Resting-state MRI data were collected to measure the topological properties of functional networks through graph theory analysis, encompassing global efficiency, local efficiency, and degree centrality. Results: Sensation seeking was positively associated with impulsivity, which, in turn, was positively linked to IGD tendency. A cross-lagged effect between impulsivity and IGD tendency was evident over a two-year timeframe. Furthermore, whole-brain local efficiency was a positive predictor of impulsivity, with centrality and efficiency of the right thalamus, along with local efficiency of the right lingual gyrus, demonstrating positive correlations with IGD tendency. Conclusion: This study revealed that sensation seeking indirectly affects IGD tendency through impulsivity, which also directly impacts IGD. Neural correlates of impulsivity included local efficiency, and of IGD tendency, included the right thalamus and lingual gyrus. These findings offer insights into IGD mechanisms and possible prevention approaches.
